Thermoelectricity offers a compelling pathway for sustainable energy conversion by directly transforming heat into electricity and vice versa, without moving parts or emissions. My research focuses on the development, characterization, and optimization of high-performance thermoelectric materials and devices. Emphasizing both n-type and p-type materials, I investigate semiconductors, nanocomposites, and hybrid systems to enhance the Seebeck coefficient, electrical conductivity, and thermal stability while minimizing thermal conductivity. Utilizing advanced synthesis techniques and computational modeling, my work aims to improve the thermoelectric figure of merit (ZT) for applications in waste heat recovery, micro-power generation, and thermal management in electronics. This research contributes to the growing demand for clean, efficient, and compact energy solutions in various industrial and environmental contexts.
Superconductivity materials exhibit zero electrical resistance and expulsion of magnetic fields below a critical temperature, offering transformative potential in energy, transportation, and quantum technologies. This research explores the design, synthesis, and characterization of both conventional and high-temperature superconductors, including cuprates, iron-based compounds, and novel layered materials. Emphasis is placed on understanding the interplay between crystal structure, doping, lattice strain, and electronic correlations that govern superconducting behavior. Advanced techniques such as cryogenic measurements, X-ray diffraction, and electron microscopy are employed to investigate superconducting phase transitions and critical parameters. By improving critical current densities, magnetic flux pinning, and operational stability, this work aims to advance the application of superconductors in energy-efficient power grids, superconducting magnets, fault current limiters, and eme
